Efficient Removal of Phenol and Bisphenol A Complex Pollutants by Activated Carbon Sphere-Based Material: Adsorption Characteristics and Mechanisms
Phenol (PHE) and bisphenol A (BPA) are common and highly hazardous phenolic organic pollutants in wastewater. However, existing research on the removal effect and mechanism of their complex pollution is insufficient. In this study, carbon spheres were synthesized via hydrothermal method using glucose as the carbon-based raw material, and anionic surfactant and thiourea were added. Activated carbon sphere-based material (ACP) were further prepared using the high-temperature activation effect of KOH. The adsorption characteristics of ACP for two phenolic pollutants (PHE and BPA) alone and in complex pollution were investigated by batch adsorption experiments. The physicochemical properties and high-efficiency removal mechanism of ACP were analyzed using characterization techniques and adsorption models, and its application potential was evaluated comparatively. The results showed that ACP has a variety of surface functional groups and a porous structure, with a BET-specific surface area of 1688.14 m2 g−1, and a polar surface with N and S co-doping. The Langmuir and pseudo-second-order kinetic models could well describe the adsorption characteristics of PHE and BPA by ACP, indicating that the adsorption is monolayer adsorption completed by boundary diffusion. The theoretical maximum adsorption capacities of PHE and BPA by ACP were 54.55 and 203.63 mg g−1, respectively, and the equilibrium time was 24 h. In the complex pollutions, the average removal rates of PHE and BPA by ACP were 50.3% and 54.8%, respectively. The high removal mechanisms were related to surface adsorption (van der Waals forces), π–π interactions, and hydrogen bonding. The adsorption effect of ACP was generally higher than that of various carbon-based adsorbents, which is worth promoting. The difference in adsorption of PHE and BPA was also explained from multiple dimensions. This study provides a scientific contribution to the removal mechanism of phenolic complex pollution and the efficient application of carbon spheres.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
